Changed from hardcoded to dinamic io inside memwrap.v related to iob-soc instance.

[Vasco-Luz]

When the IOB SoC was instantiated inside the MemWrap, its IO ports were hardcoded. This caused issues with other cores that required the IOB SoC ports to be dynamic. A modification was implemented to address this. This pull request contains the necessary changes.

where are these wires used ?

In any case, they are not needed : there are snippets that use the _o and _i directly , no assignment needed .
Please ask the team.

Is this module only used for synthesis?

[Vasco-Luz]

This is a fix so the main can be used in other cores. Just like the iob_memwrap the instance iob_soc needs to use a. Vs for the io's to get the new io's, when the iob has alterations, for example in Iob_soc_tester. The wires are used because the .vs of the iob_soc generates io's for the axi that are like .axi_awid_o(axi_awid). Instead of changing the .Vs the solution found was to temporally use assings. So this is not a change related to synthesis.

Not sure you understand: axi_m_m.vs already uses _i and _o , no need for wires. Talk to team

IOB_SOC_USE_EXTMEM wires are used to connect to axi_m_portmap wires in iob_soc instance.

Current if_gen.py does not support generating a portmap with sufixes for wires.
Removing the wires and connecting directly to iob_soc_mwrap.v ports requires adding option to add sufix to connection_name in portmaps:

# if_gen.py module
def m_portmap(port_prefix, wire_prefix, fout, bus_start=0, bus_size=1):
    for i in range(len(table)):
        if table[i]["master"] == 1:
            port = port_prefix + table[i]["name"] + suffix(table[i]["signal"]) # NOTE: port gets suffix
            connection_name = wire_prefix + table[i]["name"] # NOTE: no option to give sufix to connection_name for portmap
            write_portmap(
                port,
                connection_name,
                table[i]["width"],
                bus_start,
                bus_size,
                table[i]["description"],
                fout,
            )

This is a special case of portmap .vs since it mixes internal and external connections, hence the fix
